Re: [Flashcoders] Classes added
nothing will actually be added; Sprite is an intrinsic class, importing it merely works as typing and as a definition for compilation (the class is already in the player so it's not added to the SWF).

Very good point Glen... Although this seems kind of redundant if you import your classes and then use the qualified name to instantiate a specific class. But I fully understand what you mean.

Re: [Flashcoders] Classes added
So then it is safe to do import flash.display.*; Only if you're not going to run into any naming conflicts. I generally find it's better to only import the classes you're going to use, for a couple reasons. 1) It reduces the chance of naming conflicts (like two packages having Button classes in them). The only time you'll have to deal with naming conflicts here is if you actually need to use classes with the same name from two different packages. If you import the entire packages there's a higher chance of conflict. 2) It makes it much easier to tell, at a glance, what a class depends on. This can be beneficial in many cases. -Andy On Jan 15, 2008 11:52 AM, Helmut Granda [EMAIL PROTECTED] wrote: nothing will actually be added; Sprite is an intrinsic class, importing it merely works as typing and as a definition for compilation (the class is already in the player so it's not added to the SWF).

Re: [Flashcoders] Classes added
Hi, helmut, only the referenced classed will make it to the swf bytecode. So, if you have: import somePackage.ClassA; import somePackage.ClassB; private var _objectA:ClassA; Only the ClassA will be compiled. Of course, if you call the constructor, it'll be compiled as well. That's a traditional approach followed by Macromedia/Adobe to keep the swf's as light as possible. Since somePackage.ClassB is not actually used in your code, it'll be left out. By referencing it, you can force the compiler to include your class in the final bytecode (Not need to bother with that usually, but it helped my to prevent some aperently really odd bugs with a class compiled into various swf in a rather large project. Since many swfs holded the bytecode for the same class, the one in the first swf loaded was the actual code used -- the other definitions are discarded at runtime. If that swf was compiled with an old version of the class, then that old code was used by the app, and all the changes made to tha class would be missed at runtime. If, however, while navigating the site I happened to load first another swf that was exported with the new version of the class, I'd see the new behavior. It tripped me out for a quite a while until I realized what was going on. I fix it by forcing the main swf to compile the class just referencing it in a var declaration) If I'm not mistaken, these are equivalent. var mySprite:Sprite = new Sprite(); var mySprite:Sprite = new Sprite; However, if you don't use the parenthesis, you can't pass parameters to the constructor.

Re: [Flashcoders] Classes added
For example in the following: import flash.display.*; var mySprite:Sprite = new Sprite(); Does that means that only the Sprite class will be added or will all the classes under display will still be added? Only what you *use* will be added. import doesn't include anything, it merely states you might or might not use that package (or class definition), so it'll now where to look in case you do so. So in your case, yeah, only Sprite would be added. *If* it was a normal class or some custom class under AS2. Because in this specific example, if you're referring to AS3, nothing will actually be added; Sprite is an intrinsic class, importing it merely works as typing and as a definition for compilation (the class is already in the player so it's not added to the SWF). //Another basic question... could some one point me to a resource to understand the difference between var mySprite:Sprite = new Sprite; and //notice the end () var mySprite:Sprite = new Sprite(); I tried to google it but didnt know exactly how to find it..
